Synchronous videoconferencing has integrated the resources of text, audio, and images, and has become a popular tool in education. This study aims to explore how to strengthen students' collaborative learning and online social presence via Tencent Meeting and WeChat. Through bibliometric clustering of previous research, this study visualizes the top 10 keywords, countries, authors, organizations, and sources. Through a meticulous content analysis, it is concluded that Tencent Meeting could improve students' collaboration through forum discussion and screen sharing while increasing their social presence via open communication and group cohesion. The author constructs a collaborative model to conduct course design integrating Tencent Meeting and WeChat, making up for the deficiency of a single platform. Future research is called for exploring how blended learning platforms can better support learners' collaboration and social presence and to what extent the platforms should be combined to maximize the outcomes for learners.
